Method

Use the component shown in the laboratory Haake mixing machine use table 2 to prepare the compsn in the table 3.Pattern number is HAAKE Rheomix 600OS, and wherein drive system is as Polylab Drive RheoDrive7.It produces through Thermo Scientific.Mixing temperature is set in 185 ℃.

Use roller rotor (roller rotor),, component A and/or B component are added in the Mixing bowl, thereby and mix and reached uniform melt state in 2 minutes with the spinner velocity of 10RPM.Then component C and component D were added in 2 minutes in this alms bowl, mixed 5 minutes with 55rpm then.After mixing, mixture is taken out from Mixing bowl, be cooled to room temperature.

Through preparing the small pieces of compression moulding at 185 ℃ of compression moldings.The time of preheating is about 3 minutes, then presses down 2 minutes at 15Mpa.These small pieces are cooled to room temperature, and are cut into the sample that is suitable for the tension test of ASTM D-638IV type.

The wire rod that is used for mimic VW-1 test is through the compression molding preparation.Fig. 1 shows the schematic construction of forming mill.With diameter is the center that the single copper conductor of 0.5mm places each otch.The temperature of thermocompressor is arranged at 185 ℃.Be about 3 minutes warm up time, then pressed down 2 minutes at 13Mpa.These small pieces are cooled to room temperature, and are cut into banded wire rod (203mm X 2.5mm X 2mm), before fire retardancy test, 23 ± 2 ℃ and the annealing of 50 ± 2% relative humidity at least 24 hours.

Test

According to ASTM D638 at Instron ^TMTensile testing machine (from the Model 5565 of Instron) carries out tension test.

Shore scleroscope hardness test is carried out according to ASTM D2240.

Mimic VW-1FR test is used the rate of methane gas flow of 105ml/min in the UL94 of standard chamber, carry out less than the back pressure of 10mm water.The yellow terminal blue flame that has of burner is that 20 ± 1mm is high.Thereby the angle of burner is 45 ° prevents that in the incendiary process drippage from advancing burner tube.The test sketch is shown among Fig. 2.This wire rod bar hangs on the clamp, makes axis through the load that applies 50g in bottom end.One facial tissue flag (2cm X 0.5cm) is applied to the top of wire rod.The distance of flame base (vertex of burner oral area, highest point of burner oracle) to flag bottom is 18cm.Flame is applied 45 seconds continuously.Be recorded in the combustion processes and flame out time (AFT), not empyreumatic wire rod length (UCL) and not empyreumatic flag area percentage (Flag uncharred) after the burning.For 4 or 5 samples of every kind of preparation test.
